摘要:
The present invention relates to compositions containing a polycarbonate including a bisphenol compound and an effective amount of a bishaloformate component present in an amount sufficient to reduce the average unbound bisphenol compound level found in water after immersion in deionized water for two weeks at 40° C. of the composition to less than about 20 ppb. Also provided are methods for increasing the water resistance of a polycarbonate composition. The method involves adding an effective amount of a bishaloformate component to the polycarbonate composition such that the polycarbonate composition has an average unbound bisphenol compound level found in water after immersion in deionized water for two weeks at 40° C. of less than about 20 ppb.
摘要:
A thermoplastic molding composition having improved impact strength and a process for its preparation are disclosed. The structure of the resinous component of the composition contains carbonate structural units, polyester structural units and lactone-siloxane structural units conforming to ##STR1## wherein m is 1 to 90, n is 5 to 300, R is an alkyl or a phenyl radical, p is 2 to 12 and q is 2 to 20. The preparation of the resinous component entails reactive blending in the presence of a transesterification catalyst of polycarbonate, (co)polyester and a lactone siloxane copolymer.
摘要:
A process for making a copolymeric resin is disclosed. Accordingly, component (a) and component (b) are introduced into an extruder under conditions designed to promote reactive blending therebetween in the presence of a transesterification catalyst. Component (a) is a wet aromatic polycarbonate resin containing moisture in an amount greater than 0.02 weight percent and having units conforming to ##STR1## wherein D is a divalent residue of a dihydroxy compound. Component (b) is a lactone-siloxane block copolymer having structural units conforming to ##STR2## wherein m is 1-90, n is 60-150, R is an alkyl or a phenyl radical, p is 2-12 and q is 2-20. Surprisingly, use of moisture-containing polycarbonate in the process yields a copolymer having good properties, although a corresponding process where the lactone-siloxane block copolymer reactant has a smaller number of repeating units yields inferior product.

An adaptive user interface device capable of implementing multiple modes of input and configuration may adapt to current user inputs, and may include configuration changes. In an aspect, an adaptive user interface device may be configured for a finger sensing in a touchpad mode, and configured for stylus sensing in a digital tablet mode. In another aspect, surface features of the adaptive user interface device may change shape, such as by raising buttons in response to entering a keyboard or keypad mode. Various mechanisms may be used for raising buttons, and may enable presenting buttons in a variety of shapes and locations on the interface. The configuration of the adaptive user interface device may depend upon the user actions and user identity. Configuration modes may be organized according to many levels enabling a single user interface to support a large number of input options functionality within a limited surface area.
